Abstract
Description
Technical Field
[0001] The utility model relates to the field of rail vehicle body structures, in particular to a suspended rollover isolation mechanism for an unmanned rail vehicle. Background Art
[0002] Typically, existing unmanned vehicles in urban rail transit generally use isolation warning strips, fixed isolation poles or integral isolation doors to isolate drivers and passengers.
[0003] Isolation warning strips are generally made of fireproof curtains fixed on both sides of the interior wall panels. The curtain material is relatively soft, and when the vehicle accelerates or decelerates, passengers are prone to friction with the curtains, and the curtains cannot be used for holding onto.
[0004] Fixed isolation bars usually adopt a design similar to handrails, aiming to provide support and balance for passengers when standing. In order to ensure strength and stability and withstand sufficiently large pulling forces, they are generally fixed on the sides of interior partitions, the lower surface of the top plate, the sides of the vertical cover plates, and the surfaces of the side walls. However, they cannot be quickly disassembled and assembled, and cannot achieve rapid conversion between manned and unmanned vehicles.
[0005] The integral isolation door usually adopts aluminum honeycomb panels, which separate the driver's cab from the passenger compartment as a whole. It has many installation interfaces with the interior. When the rail vehicle is fully unmanned, it needs to be dismantled, which is a lot of work. In addition, the installation interfaces are not easy to be blocked, and the modification cost is high. Utility Model Content
[0006] The purpose of the utility model is to set up a flip-type isolation mechanism around the area where passengers are prohibited from entering, so as to play a warning role in blocking passengers from entering. When the fully automatic driving system is turned on, there is no need to do any decoration in the temporary duty area, so as to achieve the unification of the passenger compartment and the temporary duty area; when someone is driving, it plays the role of a warning line separating the driver and the passengers, providing the driver with an independent driving space to ensure the safety of vehicle operation; when no one is driving, it can be quickly retracted to the inside of the side wall to ensure the transparency of the passenger compartment and the driver's room.
[0007] In order to achieve the above-mentioned purpose, the utility model provides a suspended flip isolation mechanism for an unmanned rail vehicle, which is fixed to the vehicle body structure on the inner side of the interior wall panel and includes a fixing seat component, a latch component, a flip isolation rod component and a clamping seat component;
[0008] The flip isolation rod component is installed on the fixed seat component through a positioning pin, and the latch component is welded on the fixed seat component. The fixed seat component is welded by a first bending part, a second bending part and a third bending part. The first bending part is installed on the flip isolation rod component through a positioning pin.
[0009] The bolt assembly comprises a bolt seat, a spring, a bolt, a limit column and two stop columns. The bolt seat is welded on the second bending part. The bolt is inserted into the circular holes on both sides of the bolt seat and fixed by the limit column and the spring. The two stop columns are welded on the inner side of the bolt seat.
[0010] The flip isolation rod is composed of a handrail rod and a flip seat welded together;
[0011] The clamping seat is composed of a fixing seat and a spring clamp, and the fixing seat is fixed on the wall inside the wallboard of the vehicle body;
[0012] When the mechanism is in a fixed state, the isolation rod assembly is placed vertically, and the bottom is stuck in the card seat assembly; when the mechanism is in a working state, the bottom of the isolation rod assembly is separated from the card seat assembly and placed horizontally, the bottom is stuck in the U-shaped groove seat of the vehicle's center column, and the pin is inserted in the flip seat.
[0013] The turning seat is a U-shaped groove structure with a round hole.
[0014] The latch is inserted into the round hole of the U-shaped groove of the flip seat.
[0015] The limit posts are located on both sides of the latch pin, and the limit posts and the springs are used to fix the mechanism when the mechanism is in a fixed state or a working state.
[0016] Compared with the curtain-type isolation belt, the utility model is safer and more reliable; compared with the fixed isolation rod, it is flexible and convenient, and can provide passengers with a more spacious space after folding; compared with the integral isolation door, it has lower cost and is simple to operate, helping the vehicle to quickly realize the space switching between manned and unmanned driving, and there is no need to dismantle and modify the vehicle when it is put into unmanned operation.

[0020] Reference Figures 1 to 3 A suspended flip isolation mechanism for an unmanned rail vehicle is designed. The mechanism is fixed on a vehicle body structure on the inner side of an interior wall panel and comprises a fixed seat component 1, a latch component 2, a flip isolation rod component 3 and a clamping seat component 4.
[0021] The flip isolation rod component 3 is installed on the fixing seat component 1 through the positioning pin 8, and the latch component 2 is welded on the fixing seat component 1.
[0022] The fixing seat component 1 includes a first bending part 5, a second bending part 6 and a third bending part 7 welded together, and the first bending part 5 is installed with the flip isolation rod component 3 through a positioning pin 8.
[0023] The bolt assembly 2 includes a bolt seat 9, a spring 10, a bolt 11, a limit column 12 and a stop column 13. The bolt seat 9 is welded to the second bending part 6, the bolt 11 is inserted into the round holes on both sides of the bolt seat 9, the limit columns 12 are located on both sides of the bolt 11, and the spring 10 is used to fix the mechanism in a fixed state or a working state by the limit columns 12 and the spring 10, respectively, and two stop columns 13 are welded to the inner side of the bolt seat 9.
[0024] The overturning isolation rod component 3 is welded by a handrail rod 14 and a U-shaped overturning seat 15 with a round hole.
[0025] The card seat component 4 is composed of a fixed seat 16 and a spring card 17.
[0026] The working principle of the entire suspended flip isolation rod is as follows:
[0027] a. Fixed state: the isolation rod component 3 is placed vertically, and the bottom is clamped in the base component 4.
[0028] b. Working state: The isolation rod component 3 is placed horizontally, the bottom is stuck in the U-shaped groove seat 18 of the vehicle center column, and the latch 11 is inserted into the round hole of the flip seat 15 U-shaped groove.
[0029] c. Operation steps: When isolating, remove the isolation rod assembly 3 from the bottom card seat assembly 4, rotate it to 45°, and move it diagonally upward to make the U-shaped flip seat 15 penetrate into the first bending part 5, ensuring that the handrail rod 14 can avoid the bottom of the U-shaped groove seat 18 in a horizontal state, rotate it to a horizontal state, and move the handrail rod 14 toward the center of the vehicle body and insert it into the U-shaped groove seat 18. At this time, lift the pin 11 upward from the two stopper columns 13 and rotate it 90°, and drop the pin into the round hole of the U-shaped flip seat 15 with a round hole of the isolation rod assembly 3 to play a limiting role. When not isolating, the above steps are reversed.
[0030] The isolation mechanism adopts a flipping structure as a whole, and the flipping position is equipped with an automatic rebound limit pin. The handrail 14 has two fixing modes: horizontal and vertical. When placed horizontally, it is in the working state, and the height and width directions are limited by the stop column 13, and the rotation axis is limited by the U-shaped flip seat 15; when placed vertically, it is in the non-working state, and the bottom U-shaped spring steel fixing seat 16 is used to fix it. The handrail 14 is made of 2.5mm thick stainless steel and has an outer diameter of 35mm. This structure can ensure that the crew can isolate the passenger compartment from the temporary duty area in the shortest time, and can be hidden inside the vertical cover to achieve the unified style of the whole vehicle.
[0031] Furthermore, a space is reserved on the upper portion of the bending member 7 for the handrail rod 14 to avoid the U-shaped groove seat 18 when it is turned over, thereby ensuring that the handrail rod 14 can be smoothly inserted into the U-shaped groove seat 18.
[0032] It should be noted that the function of the spring 10 is to ensure that the latch 11 does not pop out from the two stop posts 13 when not in operation, to ensure that the latch 11 does not pop out from the round hole of the U-shaped flip seat 15 when in operation, and to prevent the latch from making abnormal noises during vehicle operation.
